Abstract: An evaporator air cooler having vertically stackable major components. A water reservoir is located within the bottom panel of the housing. A filtered media is positioned generally above the water reservoir. A fan is positioned above the water reservoir and the filter media. In this manner, the footprint of the unit is minimized. The warm air intake and the cool air discharge are located on the same side of the housing so that the unit may be placed against a wall thereby further minimizing the footprint. Automated controls are included to monitor temperature and humidity than oscillate the vertical louvers.

Abstract: A method of operating a HVAC system is provided. The method includes transferring heat between airflow and a heating element in the duct system. The heating element is configured to receive a fuel and ignite the fuel to heat the heating element. The method includes measuring a change in at least one gas property value of the airflow in the duct system using a leak detection sensor, where the change in the at least one gas property value is indicative of a gas leaked into the duct system. The method includes determining a concentration of the leaked gas based at least in part upon the change in the at least one gas property value and determining that the concentration as measured by the leak detection sensor has a negative value, where the negative value is indicative of the leaked gas comprising fuel.

Abstract: In an air conditioner, a drain extraction unit and a refrigerant pipe connecting unit may be disposed in a blocking region in which a discharge port is not provided so that a size of the discharge port may be secured and the discharge port may be uniformly disposed, thereby generating uniform airflow in a room. In a lower housing formed in a circular shape, some of components inside an indoor unit of the air conditioner may be disposed in a protrusion portion that protrudes from the circular housing, thereby facilitating the installation of the air conditioner. A condensate water collecting space disposed outside the housing may be provided in a drain tray, thereby efficiently preventing a leakage due to condensate water generated outside the housing. The housing, the drain tray, and the cover member of the air conditioner may be coupled by a coupling member coupled outside.

Abstract: A fan unit reduces the number of man-hours for a preliminary test and eliminates the need for a trial run at the time of duct connection are realized. A second controller acquires: a rotation speed of a fan motor of a second fan; a volume of air, a wind speed, or front-rear differential pressure of the second fan; and an air volume target value or a wind speed target value for the second fan, and calculates a rotation speed target value Ny for the fan motor 31b by using a first function: Ny=(Qy/Qx)2×ΔPx×{m×(Qy/Qx)×Vx+p}+n×(Qy/Qx)×Vx+q. Furthermore, when the front-rear differential pressure fluctuates and the wind speed is decreased from Vt to V, the second controller calculates a rotation speed change amount to the rotation speed target value by using a second function: ΔN=a×(Vt−V).

Abstract: An air-sending device includes a fan configured to blow air into a space, an airflow direction adjusting unit configured to adjust an airflow direction of the air blown out from the fan, and a controller configured to control the fan and the airflow direction adjusting unit. The controller is configured to, when a predetermined condition is met, execute a forced swing mode regardless of a setting made by a user for the airflow direction. In the forced swing mode, a swing operation is forcibly performed in which the airflow direction adjusting unit is controlled to change the airflow direction over time.
